When looking for a property to develop, or considering extending or refurbishing your home, it’s essential to consider potential risks to ascertain whether it’s a wise investment. You’ll assess the property market, financial goals, and environmental risks. If the property is in a flood zone, prone to bushfires, or subject to other potential hazards, you’ll need to take this into account. So, how do I know if it floods in my area? There are a variety of ways to find out; let’s discuss it.
What Are Flood Risk Areas?
A flood risk area—or flood risk zone—is a location more likely to flood due to heavy rainfall, snowmelt, storm surges, or other conditions leading to water overflow. These areas may span small suburbs or entire watershed regions, making them a key factor when choosing where to develop, buy, or invest.
Which areas are a flood risk:
- Low-lying areas such as floodplains and coastal regions.
- Areas near rivers, lakes, and coastal regions.
- Areas prone to heavy rainfall, snowfall, and tropical cyclones.
- Areas with limited natural drainage due to urbanisation and infrastructure.
- Impermeable soil or soil with poor drainage.
- Levees and dams which influence the natural flow of water.
